To all whom it may concern:

Be it known that 1, ROBERT A. GALLY, a citizen of the United States,residing at Cincinnati, in the county of Hamilton, State of Ohio, haveinvented certain new and useful Improvements in Musical-lnstrument-RollGearing Shifts and Brakes, of which the following is aspecification.

The present device secures a compact, simple and direct control of thegear shift and brakes of the roll spindles of the sheet music propellingapparatus of a self-playing musical instrument, in place of the formercomplicated and indirect apparatus in general use.

In the drawings Figure 1 is a front View of one end of a music-roll boxand gearing with the new brakes and shifter; and Fig. 2' an end view ofsame.

The right hand end 1 of a music-sheet roll-box is supported on a shelf2, and on the side of said end 1 is attached a frame carrying-theroll-gear parts, only the parts essential to the present invention beingshown. Only plates 8 and post i: of the frame are included in drawingsherein.

Upper spindle 5 is for engaging and revolvingany ordinary music-spool,and the lowerspindle 6 is forengaging and driving the take-up rollerwhich receives the music-sheet during playing. A drive-shaft 7 has apinion 8 attached thereto and adapted to engage the gear 9 attached tospindle 6 to propel the take-up spool 10 when the drive-shaft .7 is atleftward position.

A sprocket-wheel 11 is loose on drive-shaft 7 but is engaged by saidshaft- 7 through clutch pins 12 and 13 when shaft 7 is in its rightwardposition to drive the upper spindle 5 for rerolling the music-sheet. Adrivechain 11 connects large sprocket-wheel 11 to small sprocket-wheel15 on upper spindle 5-. Shift-lever 16 is hung from a bearing or pivot17 and has pin'18 engaging in an annular groove 19 in a collar 19 ondriveshaft 7. \Vhen the shift-lever 16 is moved to the left it throwsthe drive-shaft 7 and its attached pinion S to the left so that saidpinion 8 engages with the gear-wheel 9 to drive the take-up spool 10.When the shift-lever 16 is moved to the right its clutch-pin 12 engagesclutch-pin 13 of sprocket-wheel 11 to drive the chain 1% andsprocket-wheel 15 and spindle 5 to rewind theinusic-sheetfShifter-handle 21 is pivoted to shift lever 16 by a pivot or screw 22 atone end, and lies horizontally with its other end extending into theroll box near box-end 1. A stop 23 at left of lower end of lever 16detainsits motion to the left against a pull on the handle 21 and spring24, and a. stop 25 at right. of lower part of lever 16 prevents excessmotion in that direction. A notch 26 in upper edge of shifter-handle 21engages a catch or pin 27 fastened above it, and under said handle is alifting-spring 2S fastened on the shelf 2. \Vhen the handle 21 ispressed down it releases notch 26 from catch pin 27, so the handle 21can move to left to shift to operative drive of the take-up spool 10. Acove 29 in top of handle 21 gives an easy holdfor the operators fingerto move the handle 21 to the left, and the spring 241 pulling leftplepressing down of handle 21 to release its A lug 30 on.

notch 26 from catch pin 27. left end of handle 21 makes easy thepressing of the handle to the right by the operators finger. When thehandle 21 is thrown to the right the lifting spring 28 throws the handle21 upward so that the notch 26 en gages catch-pin 27 to hold the handle21, shift-lever 16 and connected parts in position for the rewinding ofthe musicby spindle The leftward pressure of spring 24L on shift-lever16 and handle 21 serves to hold the notch 26 of the handle 21 to theleft against catch pin 27 for exact opera tive position of the rewindclutch-pins 12 and 13.

The foregoing described shifter action for controlling the change fromforward to rewinding operations of the music-sheet is also well adaptedto a simplified brake system for steadying the travel of the music-sheetin both said directions.

A brake 81 acts on top of brake-wheel 32 attached on spindle 5 whichrevolves with the music-spool 33. A brake 3 L acts on under face ofbrake-wheel attached on spindle 6 which revolves with the take-up spool10. Brakes 31 and 31 have slots 36 and 37 at their ends away from theircurved shoe parts 88 and 39, and these slots 36 and 37 engagerespectively with hearing pins 40 and 41, on which they not only swingto allow the shoes 38 and 39 to bear on their respective wheels 32 and35, but the slotted construction insures a certain and perfect centeringof the curve of the shoe to the face of its corresponding wheel. Ashiftrod 42 connects together the two brakes 31 and 3-4, being hookedinto a transverse hole 43 in forward end of upper brake 31, and passedthrough a vertical hole 44 in the front end of lower brake 34. The lowerend of shift-rod 42 below the lower brake 34 is threaded and immediatelybelow the brake 34 is a regulating button 45 run on said thread of rod42 with its upper end against the lower face of lower brake 34., andbelow said regulating button 45 is another regulating button 46 run onsaid thread of rod 42 with the lower end of said lower regulating button46 bearing on top of lifter-spring 28.

When the handle 21 is in its right hand position to shift the apparatusto rewind the music-sheet on music-spool 33 by revolution of spindle 5,said handle 21 is raised by lifting spring 28 and regulating button 46is thrust up by lifting spring 28 thus pressing the shoe 39 of lowerbrake 34 against lower brake wheel 35, retarding spindle 6 and take-upspool 10 from racing and thus throwing loose the music-sheet duringslowing down of high speed rewinding, as also to cause the music-sheetto be smoothly and snugly wound on its music-spool 33. When the handle21 is moved to its left hand position the shift-lever 16 holds thepinion 8 in mesh with large gear 9 to drive the spindle 6 and take-upspool 10 for winding the music-sheet on to said take'up spool 10, whichwinding of the music-sheet causes the music-spool to revolve spindle 5and its brake wheel 32, the brake 31 then bearing its shoe 38 on thebrake wheel 32 as the handle 21 is then held down by the catch pin 27over the un-notched part of handle 21, thus locking the spring 28 fromany action on regulator 46 and shifter-rod 42, so that the shifter-rod42 and brake 34 and its shoe 39 dI'Op away from lower brake wheel 35,and upper brake 31 and its shoe 38 bear down on upper brake wheel 32 andso retard and steady the motion of spindle 5 and the music-spool 33, sothat the music-sheet is held to a steady motion and runs smoothly as itplays.

Connecting rod 48 is attached to the lower end of the shift-lever 16 toconvey motion to the air cut-off of player action and the high tensionservice for rewind, or other like purposes. 7
